Celebrate spring with these easy Lucky Charms Marshmallow Treats. A nearly 1:1 cereal to marshmallow ratio makes them extra gooey.
Matt’s favorite cereal is Lucky Charms. He lived on it when he was a bachelor in college. Cereal 3 meals a day! These days we reserve it for vacation and special occasions (getting old stinks).
Sometimes when I’m craving rice krispie treats, I make Matt happy by making these Lucky Charms Marshmallow Treats instead.

🔑 Key Ingredients
There are only 4 ingredients needed for this recipe:
- Butter. If you use salted butter, it helps to cut down on the sweetness of the cereal and marshmallows. If you only have unsalted butter, add about 1/4 teaspoon of salt.
- Marshmallows. Marshmallow treats work best if you use fresh marshmallows. If you only have stale, you can try putting a slice of bread into the marshmallow bag and sealing it. They may soften up after a day or two. But, for the best results, use fresh marshmallows.
- Vanilla Extract. For a little warm flavor.
- Cereal. You can use name brand Lucky Charms or a store brand.
⭐️ Tips for Making Lucky Charms Marshmallow Treats
These sweet cereal bars are super easy to make. Here are just a few tips:
- Be sure to stir the gently when you add the cereal to avoid crushing the marshmallows and cereal.
- Also be sure to press gently into the pan to avoid dense and hard bars.
- If you’re looking for a little something extra, try saving some marshmallows from the cereal to press into the top of the bars, drizzle with white chocolate or add sprinkles.
- Try flavored Lucky Charms or flavored marshmallows for another variation.
❓ Can I make these in the microwave?
Sure! Add the butter and marshmallow to a microwave safe bowl. Heat in 30 second increments, stirring between each, until melted and smooth. Continue with the recipe as written.
Lucky Charms Marshmallow Treats
Ingredients

- 1 teaspoon vanilla extract
- 9 cups Lucky Charms cereal
Instructions
- Generously butter a 9×13 inch baking dish. Set aside.
- In a large pot, melt the butter over low heat. If the heat is up too high, your marshmallow treats may end up hard. Melt it low and slow together.

- Remove from heat and stir in vanilla extract. Mix well and gently stir in the cereal.
- Using a piece of parchment paper or a buttered rubber spatula, gently press the treats into prepared pan. Allow to set for 30 minutes before cutting into squares.

Frequently Asked Questions
Store the bars in an airtight container at room temperature for up to 4 days.
Unsalted butter can be used in place of salted butter. Regular sized marshmallows can be used in place of the miniature marshmallows, just use a 16 ounce bag of the regular marshmallows.
This recipe makes enough to fit well into a 9×13 inch dish. If you would like to use a smaller dish, cut the recipe in half or use 2 baking dishes.
I do not recommend freezing these treats. The cereal doesn’t stand up well to being frozen and thawed.
